Conversations¶
ChatterBot supports the ability to have multiple concurrent conversations. A conversations is where the chat bot interacts with a person, and supporting multiple concurrent conversations means that the chat bot can have multiple different conversations with different people at the same time.
Conversation scope¶
If two ChatBot instances are created, each will have conversations separate from each other.
An adapter can access any conversation as long as the unique identifier for the conversation is provided.
Conversation example¶
The following example is taken from the Django ChatterBotApiView built into ChatterBot.
In this method, the unique identifiers for each chat session are being stored in Django’s
session objects. This allows different users who interact with the bot through different
web browsers to have separate conversations with the chat bot.
def post(self, request, *args, **kwargs):
"""
Return a response to the statement in the posted data.
* The JSON data should contain a 'text' attribute.
"""
input_data = json.loads(request.body.decode('utf-8'))
if 'text' not in input_data:
return JsonResponse({
'text': [
'The attribute "text" is required.'
]
}, status=400)
response = self.chatterbot.get_response(input_data)
response_data = response.serialize()
return JsonResponse(response_data, status=200)
Statements¶
ChatterBot’s statement objects represent either an input statement that the chat bot has received from a user, or an output statement that the chat bot has returned based on some input.
- class chatterbot.conversation.Statement(text, in_response_to=None, **kwargs)[source]¶
A statement represents a single spoken entity, sentence or phrase that someone can say.
- confidence¶
ChatterBot’s logic adapters assign a confidence score to the statement before it is returned. The confidence score indicates the degree of certainty with which the chat bot believes this is the correct response to the given input.
- in_response_to¶
The response attribute represents the relationship between two statements. This value of this field indicates that one statement was issued in response to another statement.
Statement-response relationship¶
ChatterBot stores knowledge of conversations as statements. Each statement can have any number of possible responses.
Each Statement object has an in_response_to reference which links the
statement to a number of other statements that it has been learned to be in response to.
The in_response_to attribute is essentially a reference to all parent statements
of the current statement.
The count of recorded statements with matching, or similar text indicates the number of times that the statement has been given as a response. This makes it possible for the chat bot to determine if a particular response is more commonly used than another.
